Our SHD cold mirrors are coated on temperature resistant glass substrates. They are flat, dielectric front surface mirrors, used in applications that require a very high reflection in the visible range. At the same time, the dichroic mirror coating system very effectively transmits most of the infrared heat energy of a light source up to approximately 2500nm, resulting in a cool light reflection. This allows the use of the mirrors in very efficient heat-light separation systems. The multilayer dielectric coating design features a good resistance against heat, moisture and abrasion. If required, our SHD cold mirrors can be modified for different transmission- and reflection ranges, as well as in regards to the cut-on and cut-off wavelengths. Please use our custom coating inquiry form, to conveniently request your customized high reflection dielectric cold mirror coating.
